2 Claims.

This invention relates to a door holder, and has for one of its objects the provision of a device which may be attached to relatively swinging parts such as a hinged door, window or the like for mechanically engaging one of the relatively swinging parts when fastened to the other to hold the two against further movement.

Another object of the invention is the provision of a device such as a suction cup, which will engage the fiat surface of a door without being permanently attached thereto so that when the device is utilized it maybe mounted as a whole upon the wall towards which the door swings.

Another object of the invention is the provision of a suction cup which will be so resiliently mounted that the resiliency in its mounting will cooperate with the attaching action of the suction cup to cause it to better engage the object to which it is desired it shall be attached, and to hold the same without strain or undue stress exerted in the suction cup or holding device which is utilized for such attachment.

Another object of the invention is the provision of a cushioning device which as well as holding the door in open position will cushion the door if it is moved to such open position with a greater momentum than is desired. I

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawing:

Fig. l is a perspective view of the corner of a room showing the door partially open with my holding device mounted on the wall, and illustrating in dotted lines the door in engagement with this holding device to be secured thereto;

Fig. 2 is a perspective view of the holding device;

Fig. 3 is a sectional view thereof illustrating the same in mounted position on the wall and also as in engagement with the surface of a door, both the door and wall being fragmentally shown;

I Fig. 4 is a top plan view of the base to which one of the tubular working members is attached;

Fig. 5 is a sectional view of one of the tubular members;

Fig. 6 is a sectional view of another tubular member;

Fig. 7 is a sectional view of the suction cup which is mounted on the tubular'member shown in Figure 6.

Door holding devices usually consist of a part secured to the door and a part secured to the wall against which or close to which it is desired the door shall be secured in open position; in order to provide a holding device which need be attached to one of the parts only, for instance as to a wall for holding the door in open position, I have provided a suction cup and I have 5 mountedthis suction cup on a slidable plunger which is backed up by a resilient element so arranged as to tension as to cause the suction cup to operate in a predetermined manner by reason of a certain amount of pressure exerted there- 10 against, after which the plunger will slide so that no undue strain need be brought upon the cup which has been impacted by a door swinging faster than is necessary to cause the suction cup to operate; and the following is a more detailed 15 description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished:

With reference to the drawing, I have provided two telescoping tubes designated I0 and II. 20 The larger of these tubes extends inwardly as at l2 to provide a shoulder l3 and a collar H, while the smaller of these tubes II is expanded outwardly as at l5 providing a shoulder IE to contact the shoulder l3 and limit the movement of 25 these tubes in an expanding direction, such as shown in Figure 3. l The diameter of the tube H is such as to be guided by the collar l4, whereas the expanded end portion I 5 will be of a diameter to be guided by the inner surface of the main 30 portion of the outer tube iii. A base comprising a disc I! having slots l8 therein receives the fingers l9 formed on the end of the tube l 0, which fingers are bent inwardly as at 20 to secure this disc in position on the tube III. A coiled spring 35 2| engages the base and the internal shoulder 22 formed by the different sizes of portions II and i5 of the inner telescopic member so as to force these tubes outwardly as illustrated in Figure 3.

A rubber suction cup 25 provided with an an- 40 nular groove 26 which receives an inwardly extending flange surrounding the cup and formed by the turned in edge 21 of the tubular member i I to secure this rubber suction cup 25 in position. As illustrated in Figs. 3 and 7, the 45 flange 21 and groove 26 are shown as being substantially in line with the marginal portion of the base of the circular wall of the cup and thus act to apply the releasing force around the outer part or edges of the cup and to the flange or 50 turned in edge 21 of the tubular member H when a pull is'exerted on the door to disengage the latter from the outer circular edges 29 of the cup. Also, the construction further acts to transmit any force of impact around the outer part 56 contraction occurs a partial vacuum will; be formed between the cup and the surface such as of a door to hold the rubber suction cup in a known manner.

I have illustrated in Figure 1 an example of the use of my device wherein the base I1 is secured i to the base board 30 of the wall 3| by means of screws 32 passing through the opening 33 in the base l1, there being a plurality of such screws, for instance four as shown in Figure 4. door 34 swinging on its hinges 35 when it strikes the suction cup 25 in its path of travel and will be held fast thereagainst, spring 2| being of such tension as to yield to take up any pressure not needed for the operation of the suction cup and at the same time cushion and slowly bring to a stop the door or the like engaged.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. A doorholder comprising a pair of telescoptelescoping members, and a base .for mounting the device on a wall surface secured to the other member.

2. A door holder comprising a pair of telescoping tubular members, a spring in the larger member to engage the end of the other member and urge the other member to extended position with relation thereto, a suction cup, mounting'means for said cup comprising a flange at the end of the smaller telescoping member, and an annular groove in said suction cup for attachment to said flange, and a rigid, non-pivoted base for mountingthe device on a wall surface secured to the other member.
